SPECIFICATION forming part of Letters Patent No. 484,759, dated October 18, 1892.

v Application filed April 3, 1891l Serial No. 391,085. (Model.)

To all whom it may concern:

Be it known that I, CLARENCE M. STINER, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to mechanism for enforcing the performance of acertain duty; and it consists of a combination of locks and keys arranged and constructed in a special manner, whereby the movement or operation of a certain lock is dependent upon the prior operation of one or more other locks.

Referring to the accompanying drawings, Figure l represents a portion of a door and its lock fitted with a portion of the devices constituting my invention. Fig. 2 represents a faucet and its lock controlling a supply of water, gas1 orother material. Fig. 3 represents a plan of the attachment to the lock on the door, the front of the casing being removed. Fig. 4 represents a side elevation of the same, with the side of the casing removed, parts being shown in section. Fig. 5' represents the lock and lock-holder used in connection with the faucet'shown in Fig. 2. Fig.

- 6 is a bottom plan of the lock shown in Fig.

5. Fig. 7 is a side elevation, with parts broken away, of the lock shown in Fig. 5, the same A being turned at an angle of ninety degrees from the position shown in Fig. 5. Fig. 8 is a plan of the lock shown -in Fig. 7. Fig. 9 is a view of a'stop used in the lock illustrated in Fig. 3.

Referring to the drawings by letters and figures, A represents the front door or main entrance of abuilding, a the lock on said door, the keyhole of which is represented by a.

B represents a lock, which is mounted upon a guideway b, permanently attached to the back of the lock a. The lock B is adapted to slide from end to end of the guideway b.

C represents a faucet controlling, say, the supply of water to the building of which A is the main entrance. The handle of this faucet is provided with a loop c for a purpose which will be hereinafter described.

Drepresents another lo'ck adapted to tit into vand removable from a lock-holder D. The latter is permanently supported upon a bracket d, secured in any suitable manner to 'or adjacent to the faucet C.

The lock B is provided with a stop b', which vwhen the same is free and is properly adjusted may be thrust into the keyhole a of the lock a, and thus prevent the insertion of the key which operates the said lock a.

As shown in the drawings, the lock B is constructed to be operated by three keys l, 2, and 3, fitting the respective keyholes shown in lock B. Each key throws a bolt b2 into its opening b3 in the stop ZJ', and thus prevents its movement. The position of the openings b3 is such that the bolts can enter them only when the stop is pushed through an opening in the bottom of the lock B and into the keyhole a of the lock a, and it is obvious that the stop prevents a movement of any of the bolts When it is withdrawn from the keyhole a.

Each key 1 2 3 is provided with a single dog which enters a notch in its bolt b2 for the purpose of moving it longitudinally. When a key has thrown its bolt, it may be removed from the lockby continuing its rotary motion until its dog registers with the keyhole and then withdrawing it.

b4 represents a bar-detent attached to the cover of the lock, which projects inward in the plane of the bolts b2.

In Fig. 3 the bolts are shown in the withdrawn position, the stop b pulled out, so that it bars the forward movement of the bolts. In order now to free the bolts, the lock B must be moved along the guideway until the stop b registers with the keyhole a. and the stop pushed into the said keyhole as far as it will go, when the holes b3 Will be presented, respectively, to the bolts b2. The bolts may now be thrown into the holes b3, thuslocking the stop b and preventing the insertion of a The keys 1 2 3 may key in the keyhole a. then be removed entirely from the lock B by continuing their rotary motion until the dogs upon them register with the keyholes, when they may be withdrawn. Before the bolts b2 are thrown the keys 1 2 3 cannot be removed, because the bar-detent b4 stands in front of the dogs on the keys. The operation of throwing the bolt carries the dog out of the plane of the bar. Pin b5 projects into slot b ICC in the stop to prevent the same from `being entirely withdrawn from the case.

The lock D consists of a cylindrical shell having within it a rotatable body d d d2, provided near its lower end with an arc-shaped bolt d3, and also being cut .away at d4 to 'form I shoulders against which a pin d5, "connected V with the shell, may abutto limit the rotary movement ot the part d d d2. Just in front of the bolt d3 is a sliding plate d6. (Shown in l dotted lines in Fig. 7.) The upper part of this plate has a cylindrical plug or bolt upon itV which is adapted *to project atome Lend into 4a recess in the shell of theilock and at the-other end rests against a spiral spring CF. This plate and spring occupies a radial slot orf chamber ot suitable shape, 'formed in the roi tatingibody d d2. The spring tends to torce,i the 'plate outward. i

dB represents another bolt arranged par-- allel to the axis of the rotating body and lo cated ina suitable chamberformed therein. It Salso is adapted to be forced into a recess or `perforation in the end of thelvshellyas shown 'in -F-ig. 5, by a spiral spring. The function of these two boltsis to prevent therotating body from turning with respect tothe Ashell containingit. The uppertportion dof the rotating Vbody is yprovided with a chamber adapted to receive one of the keys l 2 3, which is yinserted -in .the 'keyhole d. a

iD represents a lock-holder adapted to receive and hold the ylock D. Itis provided in its =bottom with .apin d10, and in 'its side with an opening d11,which when 'the lock is inserted in the holder register, respectively, with thebolt da and the plate d6. The holder is `supported on-the bracketd in such a posii tionthatthe loop @connected with the faucethandle, will @pass in'to the openingd11 when thesaid handle isswung around. e

The operation of the devices describedis as follows: The objectof these devices istolpre- -vent the duly authorizedperson from locking the building at night without having first turned od the water, gas, or other material used in thebuilding, and thusto 1pre-vent `possible waste due to the destruction ofthe con` duits. When the janitor approaches the building in the morning `to openvitjthe 'lock B with the keys in it is in thetposition shown 'in Fig. l. The janitor may therefoi'einsert the main keyinto the keyhole u and open the door. -It then becomes necessary'to turn on the metengas, &c., in the buildingfor consumption during the day, and inorder to Ado thisfhe must withdraw the keys 1 2 3 from the` lock B andusethem'to unlock the'severalfaucetsG. Toremove the keys `1l2 fhermust'slide the'lock 'B overand rpush the stop b into the keyhole a. IHe then throws'the bolts b?, thus1 locking thelstop bin the keyhole a and con-` tinuing the Yrotary movement of the keys'lfZ, and 3-until the ydogs on them register with the keyholes, withdraws them fromthe lock,

'and goes successively to the locked faucets in the building. He inserts the key in the keyhole dg, turns the rotary body d d d2, which throws the bolt (Z3 out of the loop c to permit him to swing the faucet-handle around to open the passage. When the loop c is withdrawn from the shell, the plate d6 is permitted to move outward, causing its bolt to enter the `recess in the side 4of the shell, and thus prevent the rotary movement of the bodyd d' d2 in the shell. When the key was turned with `the bolt d3, its dog was carried out of line with the keyhole d". Consequently the key cannot now be removed from the lock D. The whole -Iock D, with the key, may be removed y"from the holder D and put into a safe place until required again. This same act is performed at each ot the other faucets, and although I have shownthree keys, it is obvious that one or any 'other numbermaybe used in the same manner. When closing-'uptime arrives,the front'doorcannot be locked, because, owing to the stopb, its key cannot `be inserted in the keyhole a. To removethestop b', the keys 1 2 3 must be usedybut theycan A-not be used until they arewithdrawn from 'the locks D. .'I'n orderto be 'able to turn a key in the lock 'D,so thatit'nia'y be removed from the lock,`t`he rotary Lbody fl d Pm'ust nfirst `be freed. To do this the lock :D is Linserted inthe shell D and 'forced to the bottom. The pin 119 "will enter the perforation Lin the 'bottomof the lockDand forcethe bolt d8 in until it does 'not bar Athe rotation'oi the body d d d2. Then vthe .faucet-.handle is (swung around, closing "the gpassage as the loopfc enters the opening d11,an`dpressesthe plate d6 inward. This entirely frees =therotarybody, and the `key may nowbe 'turned to the position. Awhere it may be removed trom lthe-lock. 1in lthusturningthc 'key and 'the "rotaryibody "the bolt da is passed through v `theloop c and locks "the faucet-handlein'its cutoff position. 'The key bis then removed and carried 'to 'the "lock '13,'whereit islinserted linits rproper place and used to "throwtone of the bolts b2 out of the stop 55. Thus it will bese'en that the bolt ds and thejplate'dcarried by 1the lock, eachformsa means `forpreventing operation of the lockwhen `removed from theholder, and it will also 'be seen -that means co-operating with the 1bolt antiplate 4for,permittingthe lock to be operatedbyits 'key when said lock is placed in the holder exist inthe lpin di, which .is carried by 'the holder, and the loop fc'o'f "the faucetshandle, which also ispractically carried by theholder, since itis supported in1proper-relationthere to. as there `may b'e are secured "and'usedin :the same manner, thus 'withdrawing all the bolts b2 from lfthe stop b,"whil1 maybe then re moved from the keyhole a and the "lockB -moved back to permit of'theuse ofthe main key ofthe building onthe lock a.

The function of the blt da is "not 'readily obvious without explanation. Its purpose is to prevent the movement ot' the'rotary body without first inserting the lock in the holder.

TOO

The other -two keys or as many of them I Without this bolt it would be possible to grasp the lock D in the hand and press the bolt d6 inward either by inserting the loop c through its side or with another instrument. l It is obvious, however, that the bolt d8 and the lock-holder D may be entirely dispensed with and the lock D be permanently attached to the bracket, in which case the key Would of course remain With the lock at the faucet during the time that the building is open. ,f

Having thus describedv my lfinvention, I claiml. The combination of a lo k and key and a second lock permanently at ached to or adjacent to the rst lock and Ibodily movable with relation thereto and a stop adapted to be locked or released by the second lock and bar the keyway of the first lock, substantially as described.

2. The combination of a lock and key and a second lock attached to or adjacent to the first lock, the second lock having a stop for barring the keyway of the lirst lock, a key for the second lock, and a detentV for retaining the key in the lock When the bolt is in one of its positions, substantially as described.

3. The combination, with a lock, of a guidewayf" permanently attached. to or adjacent F,thereto and a Second lock connected With and vlock being provided with a bolt barring the keyway of the first lock, as set forth.

4. The combination of a lock and key and a second lock and key bodily movable with having a keyway and means for retaining a key therein and having, also, a stop to permit the operation of the other lock.

5. The combination, with a lock-holder and a lock fitted thereto and removable there- 4o from, of means carried by the lock for preventing its operation when removed from the holder and co-operating means carried by FRANK S. OBER.
